Problems with custom CSS

Navigation arrows not showing inside circles and video popup not scaling

Despite this:

The blue circles for the navigation buttons appear, but the white arrows (::after) don’t render.
Videos in the popup still sit in the top-left corner instead of filling/centering within the popup.

Could you advise how to properly target the navigation icons and how to get videos to scale correctly in the popup?

Thanks!

Hi there, @Novoferm

The issue with the video alignment appeared because of these line in the code:

And the arrow icons didn’t appear because you’ve used [class*="ArrowControl"] and I’ve replaced it with the more precise [class*="ArrowControl__ArrowControlContainer-sc"] here:

Please check your widget and let me know if it’s fine now

Novoferm · September 29, 2025, 1:50pm

Hi Max, I see that this is indeed working. There’s just one more thing that isn’t functioning properly: the video elements in the popup window. I’d like them to span the full width of the left column. How can I adjust this?

Max · September 29, 2025, 1:56pm

It’s possible, but the video will get cropped in this case. Would you like to proceed with this solution?

Novoferm · September 29, 2025, 2:08pm

Hi Max, Maybe we should keep it only in full width? It’s no problem if the video doesn’t completely fill the column, but I think it will look better that way.

Max · September 29, 2025, 2:15pm

Okay, I’ll ask the devs to provide a solution for this and will let you know once I have any news

Thank you for waiting!
